科普專欄–薯不揀單 - 三十秒科學–癌細胞也會自肥？

從圖中可見，癌細胞所在的環境非常複雜。547Please respect copyright.ＰＥＮＡＮＡPFXrD9wvnU
癌細胞附近不只有著各種細胞，其就近的血管大多處於參差不齊的狀態，導致營養及氧氣難以順利到達癌細胞裡頭。547Please respect copyright.ＰＥＮＡＮＡhzhk3yF4l7

在這種「逆境」之中，癌細胞究竟有何手段求生呢?547Please respect copyright.ＰＥＮＡＮＡ5D9Rf3cy1v

(圖2)在導管胰腺癌中，科學家發現癌細胞的所在位置含有大量名為CAM的細胞。547Please respect copyright.ＰＥＮＡＮＡcirzCAbyOQ

經一系列的研究後，科學家發現這些細胞竟然是協助癌細胞長大的好幫手。547Please respect copyright.ＰＥＮＡＮＡ8RCFfr4yov

在營養短缺的環境下，癌細胞迫使周遭的細胞分解蛋白質供自己所用，從而渡過難關及繼續在逆境中成長。547Please respect copyright.ＰＥＮＡＮＡZrxYjLrFhh

在老鼠的動物模型中，若然抑制CAM細胞進行自噬作用，癌細胞的體積的確是有所縮小，得以證實癌細胞會用盡身邊的一事一物從而壯大自己，在先天資源短缺的環境下亦能「自肥」。547Please respect copyright.ＰＥＮＡＮＡk1czkzklvr
